Illinois laws:
The English language is prohibited. That's right, it's a crime to speak English in Illinois.
You must contact the police of any city before entering it in an automobile.
"Eavesdropping" on your own conversation is a Class 4 Felony. (meaning you will not be able to keep your FOID card or handle guns.)
In Chicago, one may not fish while seated on the neck of a Giraffe.
However, it IS legal to protest naked in front of city hall as long as you are younger than 17 years of age and have the proper permit.
In Evanston, both bowling and trick-or-treating are prohibited.
In Fairfield County, it is illegal for "negroes" to be in the county from sunset to sunrise.
And the best "Dumb Law?"
"In Morton Grove, you may not own a handgun."
These guys appear to get it.
